dedhedjed - THANKS for the quality recommendation! Can you tell me more about what this item does or how it works please? The description says, "Food grade nylon, custom-molded to include an integral backnut. Keeps beer (and yeast sediment) out of the Transfer Valve during fermentation. Fits our Bottling Valve above, or any valve with 3/4” tapered male pipe threads." My guess is that this is like a nylon cover that fits over the male-threaded portion of the spigot that protrudes inside the bucket. Thanks again!

azingsheim - THANKS for the great sugesstion! This seems like a super simple solution. A rubber stopper might not even need to be epoxied if it were tapped in tight enough.

That is exactly what it does. You orient it so it is pointing down and then it will form a siphon when you connect a hose to the bottling spigot. It does a great job minimizing sediment transfer. Highly recommended.
